#This application is related to two U.S. patent applications, application Ser. No. 11/672,870, entitled “CABLE CONNECTOR PLUG HAVING CONTACT WITH HOOKING PORTION”, wherein the inventor is Wu-Kuang Chen et al, and application Ser. No. 11/672,872, entitled “CABLE CONNECTOR PLUG HAVING CONTACT WITH ANTI-ROTATION MEMBER”, wherein the inventor is Wu-Kuang Chen et al. Such applications have the same assignee as the present application and have been concurrently filed herewith. The disclosures of the above identified applications are incorporated herein by reference.

#1. Field of the Invention

#The present invention relates to electrical connectors, and more particularly to a cable connector plug used in a connector for transmitting audio signals or other signals.

#The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the present cable connector plug. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views, and all the views are schematic.

#FIG. 1 is an isometric view of a cable connector plug according to a preferred embodiment of the present invention.

#FIG. 2 is a side, cross-sectional view of the cable connector plug of FIG. 1, taken along line II-II thereof.

#Reference will now be made to the drawings to describe preferred embodiments of the present cable connector plug, in detail.

#Referring to FIGS. 1 and 2, a cable connector plug 20 according to a preferred embodiment of the present invention is shown. The cable connector plug 20 includes a first metallic contact 21, a second metallic contact 22, a third metallic contact 23, a fourth metallic contact 24, and a plurality of insulators 25. The metallic contacts 21, 22, 23, 24 are insulated from each other by the insulators 25.

#The first contact 21 includes a contact portion 210, an extension portion 211 extending rearwardly from the contact portion 210 along an axis of the cable connector plug 20, and a rear portion 212 extending rearwardly from the extension portion 211. The extension portion 211 includes a first columnar portion 2111, a neck portion 2112, and a second columnar portion 2113. The neck portion 2112 interconnects the first and second columnar portions 2111, 2113. The first and second columnar portions 2111, 2113 are both cylindrical. A diameter of the first columnar portion 2111 is greater than that of the second columnar portion 2113. A shape of the neck portion 2112 is generally a conical frustum that tapers from an end at the first columnar portion 2111 to an opposite end at the second columnar portion 2113.
